Waste to Wattage

In Vietnam, most energy needs are met by the burning of wood, sourced through the unsustainable logging of native forests. The National Biogas Program of Vietnam installs digesters that convert animal waste into biogas for cooking and lighting.

This avoids carbon emissions while tackling the twin problems of dangerous cooking practices and untreated animal waste. The smoke from wood-fired stoves presents significant respiratory, heart and eye problems. Clean biogas improves indoor air quality and saves an estimated 14 hours per week for women in collecting fuel, cooking and cleaning.

Many homes are also connecting their toilets to the biogas plant, further improving sanitation and hygiene. The project provides families relief from high fuel costs, mitigates exposure to health-damaging airborne pollutants and produces bio-slurry, an organic crop fertiliser.
